The purpose of this study was to examine the reliability and sources of score variation from a performance assessment of practice competencies within an occupational therapy program. Data from 99 students who participated in a practical exam were examined. A generalizability analysis of analytic, total, and overall holistic scores was completed…

In this paper the authors examine the uses of teaching performance assessments (TPAs) as resources for learning, program evaluation, and improvement in teacher education. The authors begin by outlining their conceptual framing and related research questions about the uses of TPAs as resources for program evaluation and improvement. They describe…

The goal of this study is to determine the reliability of the performance points of dentistry students regarding communication skills and to examine the scoring reliability by generalizability theory in balanced random and fixed facet (mixed design) data, considering also the interactions of student, rater and duty. The study group of the research…

Adoption of new instructional standards in science demands high-quality information about classroom practice. Teacher portfolios can be used to assess instructional practice and support teacher self-reflection anchored in authentic evidence from classrooms. This study investigated a new type of electronic portfolio tool that allows efficient…

Sparse-rated data are common in operational performance-based language tests, as an inevitable result of assigning examinee responses to a fraction of available raters. The current study investigates the precision of two generalizability-theory methods (i.e., the rating method and the subdividing method) specifically designed to accommodate the…

This study utilizes an argument-based approach to validation to examine the implications of reliability in order to further differentiate the concepts of score and decision consistency. In a methodological example, the framework of generalizability theory was used to estimate appropriate indices of score consistency and evaluations of the…

As a property of test scores, reliability/dependability constitutes an important psychometric consideration, and it underpins the validity of measurement results. A review of interpreter certification performance tests (ICPTs) reveals that (a) although reliability/dependability checking has been recognized as an important concern, its theoretical…
